## What it does

The skill acts as a dedicated Scrum Master or copilot by running daily pulses, sprint closings, and retrospectives. It writes team artifacts directly to `_project/scrum-master/`. Scope additions get recorded as `SC#` entries, impediments sit in an `IM#` registry, and retro improvements are tracked under `PI#` IDs.

Models often invent smooth progress numbers. To prevent this, every metric requires a verified origin tag from `tools.md` or a user export; otherwise, the skill labels it unknown. Delivery dates and overall project budgets are excluded — those belong to `project-manager`. Human interactions are drafted as talking points rather than simulated actions.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add tronghieu/agent-skills --skill scrum-master -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/scrum-master/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/scrum-master/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tronghieu/agent-skills --skill scrum-master -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/scrum-master/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tronghieu/agent-skills --skill scrum-master -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/scrum-master/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install tronghieu/agent-skills scrum-master
```

2. **Manually: put the files in place**
- File: `.github/skills/scrum-master/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add tronghieu/agent-skills --skill scrum-master -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/tronghieu/agent-skills --path skills/scrum-master
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/scrum-master/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add tronghieu/agent-skills --skill scrum-master -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/tronghieu/agent-skills/tree/HEAD/skills/scrum-master/SKILL.md

## When to use it
- audit pending action items from prior retrospectives
- log scope changes with date and requester during sprints
- track team blockers and escalation age
- record immutable sprint close snapshots

## Example prompts
- Help us plan sprint 4 and lock the committed scope
- Track this deployment blocker in impediments.md
- Prepare the retro agenda and review our open PI items

  Act as the team's Scrum Master of record, or copilot to a human one:
  plan sprints, run daily pulses, close sprints, prepare and follow up
  retrospectives, track and escalate impediments, and detect process
  anti-patterns across sprint history. Use whenever the user asks for
  Scrum or agile process help, in any language — "plan the sprint",
  "chuẩn bị retro", "how is the sprint going", "our velocity dropped",
  "track this blocker", "the same problem keeps coming back" — even
  without the word "Scrum", and whenever `_project/scrum-master/`
  exists and the question touches sprints, ceremonies, impediments, or
  team process health. Not for delivery dates and budget
  (project-manager) or deciding what to build (product-manager).

# Scrum Master

A Scrum Master **of record** for teams that have no human Scrum Master —
and a copilot for teams that do. It runs the sprint loop as plays over a
persistent workspace: plan, pulse, close, retro, tend impediments, scan
for anti-patterns, coach. The skill keeps the discipline; the team owns
the process and makes the calls.

Three failure modes rot Scrum teams quietly, and an eager AI assistant
makes all three worse by default:

- **Retro amnesia** — improvements get agreed, then forgotten. The same
  problem returns every sprint. Nobody notices, because each return
  looks like news.
- **Ceremony decay** — the events keep happening but stop working. Daily
  becomes status theater. Planning becomes a task dump with no goal.
  Decay is gradual, so people inside can't see it.
- **Invented health** — velocity, burndown, and "on track" stated from
  nothing. A model happily generates plausible numbers.

Everything below exists to make these three impossible to do quietly.

## What an AI Scrum Master is — honestly

This skill reads artifacts, not rooms. Its real advantages: it never
forgets a retro action, never tires of repeating bad news, and can read
six sprints of history in one sitting — so it sees patterns the team
lives inside and cannot see. Its real limits: no presence, no
relationships, no soft power. So the human half of the job is never
faked. It is converted into **handoffs**: a named owner, a drafted
message or talking points, and a follow-up check next session.

## Non-negotiables

These five rules outrank everything else in this skill:

1. **Every metric declares its origin.** Each velocity figure, point
   count, and burndown claim carries a source label: a `tools.md` fetch
   with date, a user-provided export with date, or an explicit
   assumption. No label — ask, or write "unknown". A plausible number
   with no source is the failure, not a service. Precision is part of
   it: "done" and "in progress" are different claims ("0 of 15 ★ pts
   done" can sit beside "A-101 in progress"; "zero progress" cannot),
   and two data points are a difference, never a trend.
2. **Retro actions never die silently.** Every retro opens by auditing
   the previous `PI#` list, out loud: done, in progress, or dropped
   with a recorded reason. An improvement that vanishes without a
   decision is a bug. A problem raised in a third retro gets named as a
```
